a resident of La Crosse, inthe county'ofv La Crosse 'and State of Wisconsin, have ins` 5 vented certain new and usefulv Improvements in Plows, of which the following is a This'side portion 8d is formed with a notch seated on `the frog and notch 8a on the share engages thecorner ofthe moldboard 2 and the/share is jammed against the outer or frontV face of the frog, the plowshare will haveits upper surfaceA flush with the mold-l bo'ardj and the side portion 8d will be flush with the 'landside The lower portion of the frog proj w'ardly and downwardly beyond the lower edge of the mold-board and this projecting portion is provided with upwardly and" rearvwardly inclined slots or notches 20. vThe v point of the` frog also projects forwardly 'of the moldboard and the fixedlandside. These notches are adapted-to receive keepers. 9 'whichpass through `and are secured to the plowshare lEachkeeperf) comprisesa bolt 11 anda sleevef12 having a tapered Vflange', 413 which is locked in place by the nut 13a. A similar sleeve 13 is secured to'the plowsliareV frearwardly of the'jfrogfby a bolt 11a. Notches 20, when the share isvbeing attached, vand.
